This command compares the contents of S
example, if the result of comparison is "equal", this command activates; but it does
not activate when the result is "unequal".
The FOR* command can directly input floating point numbers (for instance: F1.2)
to the S , S operands, or store floating point numbers in register D for use in
1 2
operations.
You can use this command directly to connect with the busbar.
